Which components constitute a basic neurological examination in adults?

• A. Mental status, cranial nerves, motor function, sensation, reflexes, coordination, gait and balance.
• B. Blood pressure, heart rate, respiratory rate.
• C. Abdominal reflexes only.
• D. Skin sensitivity to touch only.

Answer: (A)

A basic neurological examination in adults is designed to quickly survey the major functions of the nervous system to detect focal or diffuse problems. The components listed—mental status, cranial nerves, motor function, sensation, reflexes, coordination, and gait and balance—together cover the key domains you need for a broad overview. Mental status checks how well the brain is functioning at a conscious level: orientation, attention, memory, language, and thought processes. Cranial nerves assess the integrity of the brainstem and the nerves that control facial movement, sensation, vision, hearing, swallowing, and other head-and-neck functions. Motor function looks at muscle strength, tone, and bulk to identify weakness or abnormal movement patterns that can point to upper or lower motor neuron involvement. Sensation examines different sensory pathways—touch, pain, temperature, vibration, and proprioception—to localize sensory deficits. Reflexes test the connection between the peripheral nerves, spinal cord, and brain, helping detect nerve or spinal tract problems. Coordination tasks evaluate cerebellar and motor control through actions like rapid movements and precise finger-to-nose tests. Gait and balance assess how well the nervous system coordinates movement and balance, revealing problems that might not show up in isolated tests. The other options don’t provide a full picture: vital signs are important but focus on general physiology rather than neurological function; abdominal reflexes or skin touch alone are too narrow to represent the breadth of the nervous system’s exam. This combination of components gives a practical, comprehensive snapshot of neurologic status in a routine setting.
